Substitute Part Grouping Explanation

Substitution eligibility for the 84688-904SLF is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle, Female Sockets, High Speed
• Position Count & Pitch: 144 positions at 0.079" (2.00mm) spacing
• Physical Configuration: 5-row board edge, through-hole, right-angle mounting
• Electrical Specifications: 1A current rating, 120 signal and 24 ground contact layout
• Environmental Compliance: UL94 V-0 flammability rating, -55°C to 105°C operating range
• Series Compatibility: Metral® 1000 series

The substitute part 84688-104LF meets all these criteria while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 84688-104LF is the direct active equivalent for the obsolete 84688-904SLF. Both connectors share identical electrical and mechanical specifications within the Metral® 1000 series, ensuring functional interchangeability in board edge backplane applications.

The 84688-104LF provides additional advantages for new designs and ongoing procurement:

• Active Product Status: Ensures long-term availability and manufacturing support
• RoHS Compliance: Meets current environmental regulations for electronic components
• Gold Contact Finish: Provides enhanced corrosion resistance and contact reliability compared to unspecified finish on the obsolete variant
• Documented Packaging: Supplied in tube packaging for standardized handling and inventory management

Both parts maintain identical performance characteristics across current rating, operating temperature range, and flammability certification, supporting direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 84688-104LF directly replace the 84688-904SLF in existing designs?

A: Yes. Both connectors are electrically and mechanically identical across all specified parameters: 144 positions, 0.079" pitch, 5-row configuration, 1A current rating, and -55°C to 105°C operating range. Direct substitution is supported without PCB or assembly modifications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certifications. The 84688-904SLF is obsolete, while the 84688-104LF is active. The 84688-104LF includes RoHS compliance certification and specified gold contact finish (30.0µin), whereas the 84688-904SLF does not document these specifications.

Q: Are there packaging differences between these parts?

A: The 84688-104LF is supplied in tube packaging. The 84688-904SLF packaging specification is not documented. Tube packaging provides standardized handling and storage for production environments.

Q: Does the gold contact finish on the 84688-104LF affect compatibility?

A: No. The gold contact finish is a material enhancement that improves corrosion resistance and contact reliability. It does not affect electrical or mechanical compatibility with mating components designed for the 84688-904SLF.

Q: Are both parts certified to the same flammability and environmental standards?

A: Yes. Both connectors meet UL94 V-0 flammability rating and operate across the identical temperature range of -55°C to 105°C. The 84688-104LF additionally carries RoHS compliance certification.
